Allow name@domain.tld for OpenAlias lookups

Based on tewinget's update.
Make OpenAlias address format independent of existing DNS functions.

Add tests.

Test:

make debug-test
cd build/debug/tests/unit_tests
# test that regular DNS functions work, including IPv4 lookups.
# also test function that converts OpenAlias address format
make && ./unit_tests --gtest_filter=DNSResolver*
# test that OpenAlias addresses like donate@getmonero.org work from
# wallet tools
make && ./unit_tests --gtest_filter=AddressFromURL.Success
